cone flowers fell over

My cone flowers grew real well and then they fell over.
Any suggestions or reason why this happened. Thanks

Doug says there are two possible culprits. First not enough light will cause them to grow tall and lanky. Second, overfeeding will do the same.

Without knowing a lot more about the situation, these are the two primary causes of this problem.
